SIDE BEARING FOR RAILWAY CARS.

Application filed October 3, 1927, Serial No. 223,717. Renewed February28, 1929.

My invention relates to side bearings for railway cars.

An important object of the invention is to provide a side bearing of theabove mentioned character, which may be readily adjust-ed to differentelevations, and which is self-locking for the adjusted positions.

A further object of the invention is to provide a side bearing of theabove mentioned character which is simple in construction, strong anddurable.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings, forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same,

Figure 1 is an end elevation of a railway car truck, showing my sidebearings applied thereto,

Figure 2 is a plan view of the same,

Figure 3 is a plan view of the side bearing embodying my invention,

Figure 4 is a side elevation of the same,

Figure 5 is a longitudinal section taken on line 5-5 of Figure 3,

Figure 6 is a transverse section taken on line 6-6 of Figure 3, and,

Figure 7 is a perspective View of one of the adjustable wedges.

In the drawings, wherein for the purpose of illustration, is shown apreferred embodiment of my invention, the numeral 10 designates arailway car bolster, arranged above the usual truck bolster 11, andpivoted thereto at 12, by the means embodying the usual king-pin.Arranged upon opposite sides of the pivot 12 are my side bearipgs 13.

Each side bearing 13 embodies a preferably rectangular casing or box14:, having its longitudinal axis extending transversely of the truckbolster 11. This box is provided upon its opposite sides and adjacent toits bottom with any suitable number of ears 15, preferably formedintegral therewith, which ears are bolted to the bolster 11, as shown at16. Arranged within the casing or box 1 1 and extending longitudlnallythereof in parallel relation to the sides of the same, are partitions orwalls 17, preferably integral with the casing or box.

- These partitions are vertically arranged and are provided withvertical slots 18, extending through the tops of the same. Mountedwithin the casing 14 between the partitions 17 and the side walls 19 ofthe casing or box, are stationary wedges 20, having their upper facesinclined, and provided with teeth or ratchet teeth 21, which areinclined toward the upper ends of the wedges. While the wedges 20 areshown as made separate from the casing or box 14, they may, of course,be formed integral therewith.

Arranged upon the stationary wedges 20 are adjustable wedges 22, thetops of which are horizontal and the bottoms of which are inclined,corresponding to the inclination of the tops of the stationary wedges20. The inclined bottoms of the wedges 22 are provided with teeth orratchet teeth 23, inclined downwardly, to interfit with the teeth 21, asshown. The adjustable wedges 22 are equipped with pins 24, rigidlyattached thereto and these pins project outwardly be yond the box 14through longitudinal slots 25, formed in the sides 19. The purpose ofthese pins is to provide means for lifting the wedges 22 and effectingtheir longitudinal movement.

The numeral 26 designates a roller, mounted upon a shaft 27, which ishorizontally ar ranged within the vertical slots 18, and rest upon thehorizontal tops of the adjustable wedges 22.

In operation, the car bolster 10 has its outer portions adapted toengage or rest upon the rollers 26. When it is desired to verticallyadjust the roller 26 to elevate it, the wedges 22 are shiftedlongitudinally toward the upper end of the stationary wedges 20. Theteeth 23 of the adjustable wedge 22 will trip over the teeth 21, andwhen the adjustable wedge becomes stationary, these teeth willautomatically interlock, and hence the adjustable wedge is locked at theadjusted elevation. The wedge 22 is, therefore, self-locking, withoutthe aid of pins or the like, and there are no parts to work loose whichwould permit of the improper lowering of the wedge 22.

It is to be understood that the form of my invention, herewith shown anddescribed, is

to be taken as a preferred example of the same, and that various changesmay be made in the shape, size and arrangement of parts, withoutdeparting from the spirit of my invention, or the scope of the subjoinedclaims.

Having thus described my invention, I claim:

1. A side bearing to be arranged between a car bolster and truck bolsterupon one side of the pivot connecting such bolsters, comprising a pairof stationary Wedges arranged in spaced relation and having upperinclined faces provided with teeth, adjustable wedges having lowerinclined faces provided with teeth and mounted upon the stationarywedges, the adjustable wedges being adapted to be shifted longitudinallyof the stationary wedges and the co-acting teeth serving to lock saidwedges together, a roller arranged between the pairs of wedges, and ashaft carrying the roller and mounted upon the adjustable wedges.

2-. A side: bearing to be arranged between a car bolster and truckbolster upon one side of thefpivot connecting such bolsters,coniadjustable wedges being adapted to be shifted longitudinally of thestationary wedges and .the co-acting teeth serving to lock the wedgestogether, stationary members having substantially vertical openings, aroller arranged between the wedges, and a shaft carrying the roller andmounted Within said openings and supported by the adjustable wedges.

In testimony whereof I affix my signature.
